IMPEDANCE ANALYZER IM3570
Single-device solution for high-speed measurement, even when
switching between different measurement conditions
The need to take readings of multiple parameters under different conditions
(frequency, level) when measuring components such as capacitors sometimes
necessitates the use of multiple measuring instruments on a single
production line. Because the IM3570 is capable of making continuous
measurements at high speed under different measurement conditions, HIOKI
provides a single-instrument solution for such applications.
Twice the testing speed (compared to previous instruments)
Compared to existing HIOKI instruments such as the 3532-50, the IM3570
delivers dramatically shortened measurement times. In LCR mode, the new
instrument realizes a testing speed improvement of more than 200% compared
to the 5 ms measurement times typically obtained with the older design.
The benefits of the IM3570 are clear in settings such as production lines
where 100% inspection of electronic components is required.
Order-of-magnitude improvement in measurement repeatability
(*Over 100 measurements at 1 mΩ)
Low-ESR functional polymer capacitor designs necessitate measurement
precision in the order of several milliohms. By improving precision during
low-impedance measurement by an order of magnitude compared to previous
instruments, the IM3570 ensures operators ability to realize stable
measurement.
Extensive range of measurement frequencies
The IM3570 allows frequency band configuration at 5-digit resolution for DC
signals and within the range of 4 Hz to 5 MHz (resolution: 0.01 Hz under 1
kHz). This capability allows measurement of resonant frequencies as well as
measurement and evaluation of components in a state that approaches
operating conditions.
Fifteen measurement parameters
The IM3570 measures a total of 15 parameters, including Z and Y, and data
can be captured to a computer as needed.
Contact check function for preventing false measurement results
The IM3570 offers contact check functionality for both two- and
four-terminal measurement. By preventing measurements from being taken while
the measurement electrodes are not in contact with the object under
measurement, the instrument helps avoid inadvertent shipment of untested
products.
Broad range of measurement currents and voltages
In addition to normal open loop signal generation, the IM3570 can take into
account voltage and current dependence in constant-voltage and
constant-current modes. Users can set measurement signal levels over a broad
range extending from 5 mV to 5 V and from 10 μA to 50 mA (up to 1 MHz).
Measurement cables of up to 4m in length
Accuracy is guaranteed to a measurement cable length of 4 m thanks to a
design that reduces the effects of cable length through the use of
four-terminal-pair measurement. This feature simplifies wiring in automated
testing equipment.
